Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation
The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

UFS athlete Wayde van Niekerk proved himself as a world-class contender yet again. He grabbed silver in the 400 m sprint at the 2014 Commonwealth Games in Glasgow on Wednesday 30 July 2014.

Van Niekerk, who achieved a time of 44.68 sec in this race, took the lead at the first bend and held onto this position through the back straight before Kirani James of Granada pulled away over the final 150 m.

Lalonde Gordon of Trinidad and Tobago came third with a time of 44.78 sec.

This Commonwealth silver medal sees the Bloemfontein athlete’s magnificent year come full circle. Earlier this year, Van Niekerk broke the 15-year-old national record at the Diamond League meeting in New York with a time of 44.38 seconds.

Another star from the Free State, former Kovsie Kate Roberts, who took part in the mixed triathlon relay at the Commonwealth, also pocketed a silver medal. Her team mates were Richard Murray, Henri Schoeman and Gillian Sanders.

In addition, Neil Powell – Shimla Rugby alumnus from 2001 – played a central part in obtaining a gold medal at the Commonwealth Games. Powell is the coach of the Springbok 7s team that placed first at the Games in July 2014. 
 
On a more local level, Kovsie alumnus and SA athlete, Johan Cronje, was nominated for the Sportsperson of the Year. You can vote for him by sending ‘SPORT 4’ via sms to 43043.
